Vayssières, Jean-FrançoisMeyer, M. deOuagoussounon, I.Sinzogan, A.A.C.Adandonon, A.Korie, S.Wargui, R.B.Anato, F.M.Houngbo, H.Didier, C.Bon, H. deGoergen, Georg E.[Seasonal abundance of mango fruit flies (Diptera: Tephritidae) and ecological implications for their management in mango and cashew orchards in Benin (Centre & North)]Seasonal abundance of mango fruit flies (Diptera: Tephritidae) and ecological implications for their management in mango and cashew orchards in Benin (Centre & North)

The tritrophic interactions between mangoes (Mangifera indica), two frugivorous fly species of greateconomic significance, Bactrocera invadens and Ceratitis cosyra, and weaver ants (Oecophylla longinoda)were studied in Benin. We investigated whether Oecophylla cues affect B. invadens and C. cosyr...

Crop pests are a major constraint to the intensification of agricultural production in the tropics, with novel issues related to global change (climate, land use, biological invasions, etc.), food security and preservation of natural resources and biodiversity. A research, extension and education...


Brevault, T.Renou, A.Vayssières, Jean-FrançoisAmadji, G.Assogba-Komlan, F.Diallo, M.D.Bon, H. deDiarra, K.Hamadoun, A.Huat, J.Marnotte, P.Menozzi, P.Prudent, P.Rey, J.Sall, D.Silvie, P.Simon, S.Sinzogan, A.A.C.Soti, V.Tamo, M.Clouvel, P.[DIVECOSYS: Bringing together researchers to design ecologicallybased pest management for smallscale farming systems in West Africa]DIVECOSYS: Bringing together researchers to design ecologicallybased pest management for smallscale farming systems in West Africa

Fruit flies are pests of economic importance inWest Africa due to their quarantine status and losses recorded in fruits and vegetables. Before the introduction of exotic species of parasitoids against any exotic fruit fly species, it is fundamental to first determine the presence and monitor the ...


Vayssières, Jean-FrançoisAdandonon, A.N'Diaye, O.Sinzogan, A.A.C.Kooymann, C.Badji, K.Rey, J.Wharton, R.[Native parasitoids associated with fruit flies (Diptera: Tephritidae) in cultivated and wild fruit crops in Casamance (Senegal)]Native parasitoids associated with fruit flies (Diptera: Tephritidae) in cultivated and wild fruit crops in Casamance (Senegal)

Chemical control has highly expanded over the last 30 years in sub-Saharan Africa to reduce bio-aggressors on all crops. Pest management of fruits and vegetables by small farmers in sub-Saharan Africa have developed anarchically in a fuzzy regulation framework. Pesticide toxicity and excessive ap...

Weaver ants (Oecophylla longinoda Latreille) are used commercially to control pest insects and for protein production. In this respect fast colony growth is desirable for managed colonies. Transplantation of non-nestmate pupae to incipient colonies has been shown to boost colony growth. Our objec...

Weaver ants (Oecophylla spp.) are widely used as effective biological control agents. In order to optimize their use, ant abundance needs to be tracked. As several methods have been used to estimate ant abundance on plantation trees, abundances are not comparable between studies and no guideline ...

1 In Benin cashew plantations, yields and nut quality are lost mainly as a result of insect pests. In the present study, we investigated the effectiveness of the African weaver ant Oecophylla longinoda as a biocontrol agent against Beninese cashew pests. 2 In a 2-year study, nut yield and quality...

Fruit flies are pests of economic importance in many fruit crops. Little was known about Tephritid diversity in citrus orchards in southern Benin prior to this study. Traps baited with parapheromones were set in citrus orchards from August 2008 to August 2009 in the Atlant...
